Gartner said 25% of new mobile apps will communicate with IoT devices by 2018.
IT research and advisory firm Gartner said that organisations will need to gain proficiency in handling two dimensions of mobility amid growing convergence of devices, bots, things and people.
The firm said in a report that CIOs and IT managers will have to do better at mainstream mobility and to prepare for the post-app era.
"While users are constantly looking for new and compelling app experiences, the importance of apps in delivering services will diminish and the emergence of virtual personal assistants VPAs and bots will replace some of the functions performed by apps today.
Alternative approaches to interaction and service delivery will arise, and code will move from traditional mobile devices and apps to the cloud.
It estimates the shipment devices such as PCs, tablets, ultramobiles and mobile phones to reach 2.37 billion in 2016, with sales of wearables touching 293 million.
